What is dry ice? Discover the fascinating science behind dry ice, a marvel of modern cleaning technology.
Dry Ice: This remarkable substance is the white solid form of carbon dioxide (CO2), maintained at an astonishing -78.5 ºC. In its production process, it is condensed into a colorless liquid under a pressure of 62.50 bar, then swiftly solidified under controlled low pressure, creating an innovative cleaning tool.
Physical Properties: Dry ice is a white crystalline marvel, rapidly sublimating at room temperature with a high heat of vaporization. This process profoundly lowers ambient temperatures as it transforms from solid to gas, causing vapor to condense and sometimes form a breathtaking visual spectacle of white smoke in the air.
The Formation of Steam: The visible white smoke from dry ice is a captivating phenomenon formed by water vapor droplets or tiny ice crystals clinging to airborne dust. Dry ice boasts a simple cubic crystal structure, classifying it among molecular crystals, with each element playing a precise role in creating this unique transformation.
Crystalline Structure: The stunning symmetry of dry ice derives from its crystal formation, with its structure elegantly stacking at the vertices and centers of the cube, creating a mesmerizing display of molecular architecture.
Chemical Properties: Dry ice stands out for its chemical stability. Odorless, non-toxic, and non-combustive, it is an environmentally friendly choice. However, when carbon dioxide levels rise, it can stimulate the respiratory system, causing faster breathing and, in extreme cases, leading to suffocation risks due to hypoxia.
Hypoxia Concerns: Not only does carbon dioxide exhibit high thermal stability, with minimal decomposition at temperatures as high as 2000 ºC, but it also reacts with water to form carbonic acid, showcasing its properties as an acidic oxide. This reaction underlines the importance of careful handling.
How is dry ice made? Uncover the meticulous process of dry ice creation, where science meets innovation to deliver powerful cleaning capabilities.
Production Process: From the extraction of liquid carbon dioxide from storage tanks to transforming it into solid dry ice, this process begins with the spraying of CO2 into the dry ice machine's ice pressing chamber. This controlled throttling through the nozzle conjures a spectacular flurry of gas and snow-like dry ice formations.
Hydraulic System Activation: Once the snowflake dry ice reaches optimum quantity, a hydraulic system activates. Here, a piston deftly compresses these ethereal snowflakes into solid dry ice cubes, which are then skillfully extruded from the die end, ready for further transformation.
Final Product: These dry ice pellets, meticulously crafted to precise lengths, serve as the essential components for effective cleaning, enhancing each operation's efficiency and impact.
Principles of Dry Ice Cleaning: Explore the triad of principles that underpin dry ice cleaning, each harnessing the unique properties of dry ice for superior results.
Energy Transfer: Witness the power of kinetic energy as dry ice impacts surfaces at high velocity, initiating rapid heat transfer and sublimation. This process swiftly cools, contracts, and embrittles dirt, breaking its hold with impressive effectiveness.
Wash and Reveal: Through this energetic exchange, dirt is efficiently washed away, leaving cleaned surfaces pristine.
Low Temperature Cracking: Explore how the differential temperature and expansion coefficients between materials fracture bonds, as dry ice pellets freeze dirt, rendering it brittle and fragile.
Crack Formation: This results in the creation of 'cracks' that compromise mechanical properties, facilitating the effortless removal of dirt from surfaces.
Micro Explosion: A phenomenon where, after penetrating cracks, dry ice particles sublime in milliseconds, expanding massively to dislodge and peel off dirt, achieving remarkable cleaning effectiveness.
Industry Application: Dry ice cleaning is revolutionizing the way industries maintain cleanliness, offering a non-invasive solution to preserving the integrity of various materials.
Applications Galore: From metal surfaces to delicate molds, production equipment, and even ancient relics, dry ice cleaning is a versatile, non-corrosive method. It eliminates the need for mold cooling or disassembly, protecting against chemical and mechanical damage.

Cleaning Method and Working Principle of CHIRUI Pellet Dry Ice Cleaning
Our method, akin to blasting with steel, glass, or plastic sand, propels dry ice particles via high-pressure airflow. These particles impact the target surface, where they instantly vaporize, creating a unique, efficient cleaning action.
The genius of our dry ice technique lies in its rapid sublimation on impact. This momentum disappearance leads to an immediate heat exchange between dry ice and the cleaning surface, triggering a powerful cleaning response.
Solid CO2 swiftly transitions to gas, expanding nearly 800-fold in milliseconds, producing a 'micro explosion' at the point of contact. Harness the power of sublimation for unparalleled cleaning effectiveness with CO2's innate volatility.
